thermal
According to Charles’s law, what happens to the volume of a gas when temperature increases while pressure remains constant?
The volume increases.
aporization that occurs only at the surface of a liquid is ______________________
evaporation
Flexible containers can appear crushed when pressure inside decreases because the external pressure becomes _____________ than the internal pressure pushing the container inward
larger
_____________________ ,a French Scientist, states that volume of a gas is directly proportional to its temperature
Jaques Charles
In order for water particles to evaporate, they have to have enough kinetic energy to overcome air ____________
pressure
What term describes a decrease in volume as temperature decreases?
thermal contraction
When temperature increases in a rigid sealed container, which gas property changes and why?
Pressure increases because particles collide more often and with greater force.
What causes pressure in a gas?
Collisions of gas particles with the container’s walls.
How do melting and freezing points compare?
they are the same
Which process requires removal of thermal energy?
condensation/freezing
Dew forming on the grass in the morning is an example of _______________
condensation
______________ is a measure related to average kinetic energy
temperature
During melting temperature _____________
reamins constant until all of the solid becomes liquid
_______________ is the changing of a liquid to a gas
vaporization
___________________ is The amount of thermal energy transferred from a higher-temperature region to a lower-temperature region
heat
What causes pressure to change when particle speed increases?
Increased particle speed raises collision frequency and force on container walls, raising pressure
